This seems to be what I am looking for. That was very helpful. Thank you. Erdem From: vlknkls at gmail.com Date: Wed, 16 Sep 2015 16:25:29 +0000 Subject: Re: [llvm-dev] How to add NOP? To: erdemderebasoglu at hotmail.com; llvm-dev at lists.llvm.org Use MachineInstr::memoperands() function to get memory operands then you can get the address space by using MachineMemOperand::getAddrSpace()....

I would like to convert a C file that uses OpenMP library to X86 code with a condition: I want to insert a NOP before each instruction that does a private memory access.I have written an optimization pass that inserts an inline assembly call (NOP) but it is applied at IR level, and I cannot determine where to insert it. How can I use LLVM to add NOPs accordingly? Thanks. --------------
